That's because you've got lots of stuff to keep If you're doing large Mathematica calculations, you had better get the extra memory *and* the faster processor. Mma is a major memory hog (at least 1.2 is), and you're in for a lot of wear and tear on your hard drive at 8M or even 16M. For Mma, a 25 MHz 040 with 32M will be a *lot* faster than a 1 GHz 040 with 8M, at least for the kind of stuff I was doing, since the processor would be waiting for pages to swap in.
